Definitions

  • the invention relates to a method and a device for treating containers according to the preambles of claims 1 and 10.
  • Container treatment machines usually transfer the treated containers to a transport device on which the treated containers are transported to another container treatment machine.
  • a block with a blow molding machine, labeling machine and filler/capper only changes the beverage on a machine
  • the changeover process is completed after a very short time, e.g. 10 minutes.
  • the block could then theoretically produce. Since there may still be containers from the previous production in the feed of the following machine, e.g. a disposable packer, e.g. because the disposable packer has not yet been completely emptied by the operator, the packer has not yet released the packer for the new production on the block.
  • the reason for the non-approval is that mixing containers of the first type and containers of the second type on a transport route must be avoided.
  • Another example is the transport of packers, especially one-way packers, to the palletizer. If the palletizer is not yet ready for production, the one-way packer cannot yet produce. This can also lead to a loss of production time.
  • DE102015211380 A1 discloses a method and a device for filling containers, wherein crates with empty containers pass through at least one treatment station via a transport device, the transport device comprising at least one separating device.
  • the object of the present invention is to provide a method and a device for treating containers which largely avoid production losses in the plant when changing from containers of a first type A to a second type B and enable higher plant availability.
  • containers are treated with at least two treatment machines.
  • a transport device for transporting the containers is located between the treatment machines.
  • a separating device between a first and a second transport section is activated according to the present invention, the separating device separating the container stream between the first and second transport section.
  • the separating device is activated after the first transport section of containers of type A has been emptied.
  • the transport sections are directly adjacent to one another in the transport direction of the transporters.
  • containers are understood as meaning individual containers or also a combination of containers, for example a bundle.
  • the containers of type A differ from the containers of type B, for example, by the filled product or the shape or geometry of the container and a resulting different container size or container shape.
  • the separating device can therefore effectively separate the container stream of different containers, since type B containers are backed up in front of the separating device. Since the separating device is only activated when the first container section already has no more containers of type A, it can be ensured that the containers of type A and B are not mixed up. Even if there is a malfunction in a downstream unit, for example the downstream container treatment machine or the upstream conveyors, the two types will not mix if there is a build-up.
  • containers of the second type B can be conveyed into the first transport section while containers of the first type A are still in the second transport section are located and are conveyed out of this transport section.
  • the first container treatment machine is already released for production if the second container treatment machine has not yet run empty. This saves a lot of time because if the changeover process of the first container treatment machine is relatively quick, for example if only the filled product and a corresponding labeling etc. is changed over, production can start immediately after the changeover without a long wait. It is safest that the first container treatment machine is only released when the separating device has already been activated.
  • the first container treatment machine it is also possible, particularly in the case of a longer first transport section, for the first container treatment machine to be released directly after the changeover process, before the separating device has been activated. It is essential, however, that the separating device is activated after the first transport section of containers of type A has run empty and before a container of the second type B leaves the first transport section.
  • the point in time when the first container of the second type B is still on the first transport section can be determined, for example, via the point in time at which production of the first container treatment machine begins, as well as the conveying speed and the conveying path.
  • the separating device between the first and second transport section can subsequently be deactivated again in such a way that the accumulated and subsequent containers of type B are transported through the second transport section to i.e. in the direction of the second container treatment machine.
  • the containers of the second type run through the entire second transport section.
  • the present invention makes it possible for production to start very quickly after the first container treatment machine has been changed over, and yet mixing of the containers of type A and containers of type B can be prevented by the separating device.
  • the loss of production time when changing over can thus be effectively minimized and the system availability increased.
  • the invention can easily be implemented with a single transport path, ie without the use of switches and parallel paths and secondary buffers.
  • the separating device is deactivated after the second transport section has run empty of the type A containers.
  • the separating device is additionally only deactivated when the second container treatment machine is set up to treat the type B containers.
  • the machine can, for example, output a corresponding signal to a control device, which also controls the separating device. This is particularly advantageous if the separating device is located relatively close to the second container treatment machine. This ensures trouble-free operation.
  • separating devices it is also possible, particularly in the case of longer transport routes, for several separating devices to be provided between the first and second treatment machine, with a further n+2nd transport section being provided in particular after the n+1st transport section, with an n+1st separating device between the n+1st and n+2nd transport section is activated after the n+1st transport section has run empty from the containers of type A and
  • Containers of the second type are conveyed into the n+1st transport section, while containers of type A are transported out of the n+2nd transport section, with the n+1st separating device preferably being deactivated when the n+2nd transport section has run empty (and preferably at the same time the second container handling machine is ready for type B containers).
  • the transport sections are arranged adjacent to one another in the transport direction. This means in particular that a subsequent transport section is arranged at the end of the preceding transport section.
  • an n+1st separating device for example a second separating device
  • the n+1st transport section ie the second transport section of the n+1st, eg second transport device
  • the buffer size for the individual separating devices can be selected to be smaller than for a single separating device, since the buffers are divided up along the transport route.
  • the separating device comprises a conveyor between the first and second transport section or between the nth and n+1th transport section, which stops when the separating device is activated, so that the containers accumulate on and in front of the conveyor. This is particularly easy to implement and can accumulate the containers particularly gently.
  • the transport device comprises a plurality of individually controllable transporters, with the at least one separating device comprising one of the transporters, which stops when the separating device is activated in such a way that the containers accumulate, with the transporter acting as a separating device in the end area (i.e. the end facing away from the first container treatment machine) of the respective transport section is arranged or the transport section of the conveyor corresponds to the transport section. If a specific transport dog is assigned to a respective separating device, the at least two transport sections each have a predetermined length and a predetermined position.
  • the transport sections are provided, each of which corresponds to the transport path of successive transporters. This means that the length of the transport section corresponds to the transport section of the transporter. Thus, several shorter transport sections are provided. Then, when the transporters of containers of type A have each run empty, the respectively empty transporter that is in the front position behind the containers of type A in the transport direction can be stopped until the transporter following in the transport direction of containers of type A has run empty , which is then stopped in turn, whereby the previous conveyor is restarted. This is particularly suitable for transport routes that are not intended for accumulation operation. According to the invention, the activated separating devices follow the movement of the container of the first type A.
  • the separating device may include a mechanical damming element that is introduced into the transport path of the containers.
  • a corresponding accumulation element can be implemented, for example, in such a way that a stopper with a pneumatic cylinder pivots onto the conveyor, which stops the incoming articles.
  • the use of the conveyor as part of the separating device is advantageous, however, since a plurality of conveyors, which can be controlled separately from one another, are usually provided between a first and second container machine.
  • the containers of the first type A and the containers of the second type B differ only to the extent that the same transport device can be used between the first container treatment machine and the second container treatment machine. This is particularly the case when the same container is used, only with a different food filling. In the case of corresponding containers, the changeover work on the container treatment machines is also less, so that, for example, the first container treatment machine is available relatively quickly. It is then particularly advantageous if the production of the type B containers can be started before the second container treatment machine runs empty and the type B containers can then be accumulated in front of the separating device.
  • At least one sensor on the first and/or second (or n+1) transport section can be used to determine whether containers of the first type A are in the first and/or second (or n+1) transport section condition.
  • the number of containers of type A arriving on the first and/or second (or n+1st) transport section and the number of containers from the first and/or second ( or n+1st) transport section are counted, the difference is determined and the number of containers located on the first and/or second (or n+1st) transport section is determined. This is just one example of how it can be determined using sensors or counting devices.
  • the first container treatment machine generates a signal for the end of the production of containers of type A and forwards this signal to the control device. Depending on this signal can then be determined whether containers of type A are on the first or second (or n+1st) transport section or whether the first transport section is free of containers of type A.
  • the last type A container produced by the first container treatment machine can also be tracked, since the transport speed, the transport route and thus the theoretical time for transporting the container is known or stored. In this way it can also be deduced whether this last container has definitely passed through the first transport section and is not still in this area.
  • a number of items of information for example sensor information, theoretically determined positions of a last container, etc., can also be linked with one another in order to deduce that a separating device can be activated and, if necessary, to deduce, for example, that the second container treatment machine can run empty and be converted if there is no Type A container is more on the transport sections between the first container treatment machine and the second container treatment machine.
  • a device for carrying out the method according to the invention comprises at least a first and a second treatment machine.
  • a transport device with at least two transport sections is provided between the first and second container treatment machines.
  • the transport device can, for example, comprise a plurality of transporters arranged in a row.
  • the device also includes a separating device between the first and second container treatment machine, which when activated can separate the container flow between the first and second container treatment machine, so that no containers can be transported from the first transport section into the second transport section.
  • the device comprises a control device which is designed in such a way that when changing from containers of type A to containers of type B it can activate the separating device between a first and second separating section in such a way that containers of type B are already fed to the first transport section while at the same time without mixing the containers of type A and B, containers of type A can be conveyed out of the second transport section, in which case the control device can then deactivate the separating element again so that the containers of type B are transported via the second transport section to the second container treatment machine can become.
  • the separating device enables different containers in the container flow to be separated. It is advantageous that the first area can be filled with containers of type B, while at the same time the second transport section can be emptied of containers of type A without the containers mixing and/or running over one another or damming up.
  • the device comprises a plurality of separating devices which are arranged one behind the other and are separated from one another by corresponding transport sections.
  • the device also includes a detection device that detects whether the first transport section of containers of type A has run empty during the product change and that generates a signal when the first transport section has run empty (i.e. the transport section that is arranged in front of the separating device - for example if there are several separating devices). , on the basis of which the control device activates the separating device.

  • the separating device 6 1 is activated by the control device 10 .
  • the conveyor 8 3 which is 4 is shown in dashed lines stopped. This means that the container treatment machine 2 1 does not have to wait until the packer 2 2 has been emptied of type A containers, but that the production of the container treatment machine 2 1 can start beforehand, either when the separating device, as in 4 shown is activated, but also before. It only has to be ensured that the containers of type B are still in front of the separating device in the transport direction, ie in the first transport section 4 1 , when the separating device 6 1 is activated.
  • the separating device brings with it the advantage that containers of type B can already enter the transport path between the first and second container treatment machine, while the last containers of type A are still leaving the transport path 4 2 . Even if there are blockages on the packer 2 2 or on the conveyors after the separating device 6 1 , it can be reliably prevented that the containers of type A and B get mixed up.
  • figure 5 shows a state in which the second transport section 4 2 has already completely emptied of type A containers. If it is determined by an appropriate device that there are no more containers of type A in the second transport section 4 2 , ie here that the packer inlet has run empty, how can this be done? 6 shows that the separation can be canceled and containers of type B can now also be transported in the second transport section 4 2 in the direction of the second container treatment machine, here packer 2 2 . The separation can be canceled by putting the conveyor 8 3 back into operation, for example. In the area of the conveyor 8 3 , a so-called buffer section can be formed, which is designed in such a way that it can buffer the containers that have accumulated. Now it is possible, for example, that this buffer is drawn empty by an increased speed of the conveyors, which are arranged after the separating device. The buffer can also be emptied if the packer overperforms.
  • how out 6 shows, after the packer has run empty, the packer is switched over to the production of bundles with containers B.
  • the separation has already been canceled before the packer has been completely switched over.
  • the separation can only be canceled when the packer generates a signal that a changeover has taken place.
  • eliminating the separation beforehand brings with it a time advantage, while still ensuring that the products do not get mixed up.
  • packer is ready for packs of type B but is not yet producing.
  • the control device 10 activates the first separating device 6' 1 , with the conveyor 8' 3 for example being stopped in this exemplary embodiment.
  • the advantage of several separating devices is that the buffer size can be selected to be smaller for the individual separating devices, since the buffers are divided up along the transport route. How out 9 and 10 shows, the last containers of type A are now also moving out of the third transport section 4'3 . If the palletizer how off 10 shows that it has run empty, it can be switched to type B containers.
  • the second separating device 6' 2 is also deactivated by the control device 10. This can take place when it is recognized that there are no containers of type A in the section 4' 3 following the separating device, ie the palletizer inlet or inlet has run empty.
  • the palletizer can also have its own stop device that can be switched on and off by the palletizer itself. If the separating device is located relatively close to the palletizer, it can also make sense that the separation is only canceled when the palletizer generates a signal that it is ready for operation for packs with type B containers. Since the separation has been removed, the type B containers can now also pass through the third transport section to the palletizer, with the production of type B containers now running continuously and the changeover being completed.
  • a separation is always canceled when it is determined that there are no more containers of the preceding type A in a specific subsequent transport section.
  • a fault is detected in a container treatment machine arranged downstream of the separating device or in a conveyor arranged downstream, so that a backlog is to be expected or a backlog has already occurred, a fault signal is sent to the control device 10 and the separating device is not deactivated.
  • the 12-20 show the device 1a of FIG Figures 1-11 , ie in which the block 2 1 represents the first container treatment machine and the packer 2 2 represents the second container treatment machine.
  • the device essentially corresponds to that in 1 described device, but in addition between block 2 1 and packer 2 2 a heating device 12 is provided.
  • the heating device can, for example, be a pasteurizer or a device for heating the products, for example to prevent condensation.
  • the heating device 12 can also be a cooling device for cooling hot-filled products. In any case, the transport speed through the heating device 12 is lower than the transport speed with the conveyors 8 1 -8 5 .
  • a first transport section 4 1 extends from the block 2 1 to the heating device, a second transport section extends through the heating device 12, for example to the end of the first conveyor after the heating device 12.
  • a third transport section 4 3 extends in an area to of the heater 12 and in front of the packer 2 2 .
  • the first separating device 6 1 comprises the conveyor 8 5 and the second separating device 6 2 comprises the conveyor 8 6 .
  • the respective conveyors, which are assigned to the separating devices, are therefore, as already explained, at the end of the respective transport section, since they have to be run empty before they are stopped.
  • 13 now shows a process step in which the block produces containers of type A, which are heated in the heater 12, for example. After heating, the type A containers are then conveyed to packer 2 2 , which produces packs with type A containers.
  • the block is as from 14 shows, switched to containers of type B, so that the corresponding conveyors in the first transport section 4 1 run empty. After the block or the first container treatment machine 2 1 has been converted to type B containers, the block can immediately begin to produce the type B containers. If the last conveyor 8 5 is empty, ie there are no more containers of type A on the first transport section 4 1 , as in 15 is shown, the separating element 6 1 is activated, for example by the conveyor 8 5 stopping. Thus, the transport section 4 1 is separated from the transport section 4 2 and the containers of the different types cannot be mixed up. Furthermore, the transport section 4 2 in the heating device 12 slowly runs empty and the containers of type A move in the direction of the packer 2 2 , see also here 16 .
  • the containers of type B accumulate in front of the activated separating device 6 1 .
  • the first separating device 6 1 can be deactivated. If the second transport section 4 2 has run empty of containers of type A, as from 18 can be recognized, the conveyor 8 6 can be stopped, ie the separating device 6 2 can be activated. Since the containers of type B, which are now entering the heating device 12, remain in the heating device 12 for a longer period of time anyway, no separate or only a small buffer area is necessary.
  • the containers of type A now run out in the direction of the packer, with the last container 3 E moving through the third transport section 4 3 . How out 19 emerges, the third transport section 4 3 is now running empty and the packer is still producing packs of type A. If it is determined that there are no packs of type B in the third transport section 4 3 , the second separating device 6 2 is deactivated, i.e. the Feed dog 8 6 starts again. This means that containers of type B can now also enter the third transport section 4 3 . Now the empty packer becomes 2 2 figure 20 converted to type B containers and the type B containers can be processed in Packer 2 2 . This means that the change or conversion of production from type A to type B has been completed.
  • the last separating device is only deactivated when the subsequent container treatment machine has been completely emptied of the previous type of container and/or all previous containers have been transferred to the subsequent container treatment machine.
  • a corresponding container treatment machine can generate a corresponding signal for this purpose.
  • FIG. 21a-d illustrated embodiment is also particularly advantageous for non-accumulating transport routes with multiple conveyors.
  • a device is shown here that has, for example, a packer as the first container treatment machine and a palletizer as the second container treatment machine 2 3 .
  • the transport device 7 again comprises a plurality of transporters 8a-8n which are arranged one behind the other.
  • the transport sections 4 n each correspond to the transport route of a transporter 8 n , as shown in FIG Figure 21a emerges. This means when, for example, the first conveyor 8a has run empty is, ie it is determined that the first transport section 4 1 has run empty, the corresponding conveyor 8 a can be shut down.
  • the first transport section can also extend over several conveyors, here for example over three, as represented by section 4-10 , with the last conveyor 8 c then acting as a separating device 6 1 functions when section 4 10 has run out. If it is determined that the section 4 4 downstream of the separating device 6 1 has also run empty, as shown in FIG Figure 21a emerges, the associated conveyor 8d is stopped ( Figure 21b ) and thus serves for separation.
  • the number of containers of type A on the container transport 7 can be determined by counting the containers in the block, ie here the first container treatment machine 21 and by counting the individual containers in the packer of type A. By forming the difference between the packs on the packer and packs on the palletizer, the number of containers or packs on the transport route between packers palletizers can be determined. In the 22 only type A containers are produced.
  • a separation 6' 1 is activated here to prevent mixing of the different grades, even if there is a fault in the palletizer. As previously described, this separation can be deactivated when the transport section has run empty after this separation device.
